    9 description: |
   10   The Audio Hub (AHUB) comprises a collection of hardware accelerators
   11   for audio pre-processing, post-processing and a programmable full
   12   crossbar for routing audio data across these accelerators. It has
   13   external interfaces such as I2S, DMIC, DSPK. It interfaces with ADMA
   14   engine through ADMAIF.

   64       These are connected to ACIF interfaces of AHUB clients. Thus the

   66       have depending on the SoC revision.
